White on White: A Mercer Island Bath

Bathroom Design
Mercer Island
Marble + Brass
Master Bath

A Mercer Island master bath built entirely in white — marble, tile, fixtures — with gold hardware as the single, deliberate counterpoint.

This bathroom has one idea and commits to it completely: white. Not off-white, not cream — white. Marble tiles, white ceramic, white walls, white ceiling. It takes design confidence to build a monochromatic space this single-minded and have it read as luxury rather than sterility.

The gold hardware is what holds it together, giving every surface a point of reference without breaking the palette. Every surface is practical. The marble was sealed properly. The gold fixtures are solid brass, not plated.

Designed Around One Commitment

Monochromatic design only works if the commitment is total. One exception — a colored towel hook, an out-of-palette tile — and the whole composition reads as unresolved. This bathroom was designed with that discipline in mind. Every specification was evaluated against the white-and-gold constraint before it was approved.

Marble was selected for its veining: subtle enough to stay within the white family, present enough to give the surfaces texture and life. Flat white would have felt clinical. The veining keeps it warm.

The Work Begins With One Conversation

We hold a limited number of consultations each month and are selective about the projects we take on. If you’re ready to discuss yours, we’d like to hear about it.

The Challenge

Restraint as a Design Act

The client wanted something ornate. The interpretation of “ornate” here was material quality rather than surface decoration — the ornamentation comes from the marble’s natural variation and the weight of solid brass, not from moldings or applied detail.

Managing a completely white bathroom without it feeling cold required careful attention to light sources, surface finish variation (honed vs. polished), and the warmth the gold hardware introduced as a system rather than an accent.

Our Design Approach

Specified at the Slab Level

Material sourcing for a project like this starts with the marble slab. We reviewed slabs in person before selecting — the veining pattern in a tile sample doesn’t tell you how the full installation will read. The selected stone had to work as a large field, not just as a sample chip.

Fixture selection was about weight and finish consistency. Every piece of gold hardware — faucets, towel bars, robe hooks — came from the same manufacturer to ensure the finish tone matched across the room. Mixed sourcing creates subtle finish inconsistencies that undermine a tight palette.

Lighting was designed to enhance the marble’s warmth rather than create a cool, shadowless environment. Warm-temperature LED sources were specified throughout, positioned to graze the tile surfaces and bring out the veining.

Common Questions

Frequently Asked

Surface variation is the key. Honed marble reads differently than polished marble even in the same color family. Warm-toned lighting makes white surfaces read as cream rather than clinical. And a single deliberate accent — in this case solid brass — gives the eye a focal point that anchors the whole room.

Yes, when it’s properly specified and sealed. We specify marble for bathroom applications regularly. The key is choosing the right stone (some marbles are more porous than others), having it sealed properly before installation, and understanding that it will develop a patina over time — which many clients consider part of its character.

We review slabs in person, not just samples. A marble tile sample tells you the color and veining pattern at the chip level, but it doesn’t show you how a full installation reads from across the room. We visit stone yards and select based on the full slab, often booking sequential slabs from the same block to ensure consistency.

Gold and brass have warmth that chrome doesn’t. In a white-dominant room, you need the accent hardware to read as warm — cool metal against a white palette can tip toward cold. Brass also ages gracefully; it develops depth rather than showing wear the way chrome does.

We coordinate with your contractor through the design and specification phase and provide detailed documentation so they can execute precisely. For clients who need more hands-on support during construction, we offer construction administration services where we visit the site at key milestones.


Begin Your Project

Your space should hold you. Every time you walk in.

The work in this portfolio is the standard we hold ourselves to on every project — not just the celebrated ones. We take on a limited number of engagements each year, which means the projects we commit to receive our full attention from the first conversation through the final installation.

If you’re considering a renovation, a new build, or a full redesign, tell us about your space. We’ll tell you honestly whether we’re the right fit — and what working together would look like.
